What frida_inject_library_file does on Ya Frida
AI agents invoke frida_inject_library_file to trigger actions in Ya Frida. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.
Why frida_inject_library_file is rated High
Library injection (e.g., via Frida's inject_library_file) loads and executes arbitrary native code into a running process. This is a classic code execution primitive — it attaches to a process and forces it to load a shared library, executing its initialization code. Even with an empty description, the tool name unambiguously describes this behavior.
From the tool's definition Tool name 'frida_inject_library_file' combined with server description mentioning 'dynamic instrumentation', 'scripts', and 'memory' operations. Injection of a library file into a process is a code execution operation.
Attacks that exploit this kind of access
The rule that runs frida_inject_library_file safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Ya Frida, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For frida_inject_library_file, this is the rule to start with:
frida_inject_library_file stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Ya Frida, apply this rule, and every frida_inject_library_file call is checked against it from then on.

frida_inject_library_file is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the frida_inject_library_file rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
